[0030] Reference Figures 1-6 An emergency iron-blocking device for an electric arc furnace includes a support platform 1. A motor 2 is fixedly connected to the lower surface of the support platform 1, and the support platform 1 supports and fixes the motor 2. A transmission shaft 3 is fixedly installed at the output end of the motor 2. The outer wall of the transmission shaft 3 is rotatably connected to the inside of the support platform 1. One end of a rotating plate 4 is fixedly connected to the outer wall of the transmission shaft 3. The other end of the rotating plate 4 is fixedly connected to a connecting shaft 5. One end of an adjusting plate 6 is rotatably connected to the outer wall of the connecting shaft 5, and the connecting shaft 5 connects the rotating plate 4 and the adjusting plate 6. The other end of the adjusting plate 6 is rotatably connected to a fixed shaft 7. A slider 8 is fixedly connected to the outer wall of the fixed shaft 7. A limit frame 9 is slidably connected to the outer wall of the slider 8. The outer wall of the limit frame 9 is fixedly connected to the outer wall of the support platform 1, and the support platform 1 supports and fixes the limit frame 9. A pushing component 10 is provided on the lower surface of the slider 8.

[0031] The usage process of the emergency taphole sealing device for a submerged arc furnace provided by this utility model is as follows:

[0032] When needed, motor 2 is started. The driving action of motor 2 enables transmission shaft 3 to rotate stably inside support platform 1. The transmission action of transmission shaft 3 drives rotating plate 4 to rotate synchronously. Rotating plate 4 fixes connecting shaft 5. The connecting action of connecting shaft 5 enables adjusting plate 6 to rotate with connecting shaft 5. Adjusting plate 6 supports fixed shaft 7. Slider 8 fixes fixed shaft 7. Slider 8 is set on the inner wall of limit frame 9. When fixed shaft 7 rotates, it drives slider 8 to slide against the inner wall of limit frame 9 to avoid deviation during sliding. The sliding of slider 8 can drive pushing component 10 to slide synchronously. Through precise control, the accuracy and consistency of the movement trajectory of sealing plate 11 can be ensured, realizing automated iron-blocking operation.

[0033] Reference Figure 3 The pushing component 10 includes a connecting block 1001. The upper surface of the connecting block 1001 is fixedly connected to the lower surface of the slider 8. The slider 8 fixes the connecting block 1001. The outer wall of the connecting block 1001 is slidably connected to the inner wall of the limiting frame 9. A push rod 1002 is fixedly connected to the outer wall of the connecting block 1001. The outer wall of the push rod 1002 is slidably connected to the inside of the limiting frame 9.

[0034] The usage process of the emergency taphole sealing device for a submerged arc furnace provided by this utility model is as follows:

[0035] When slider 8 slides, it will drive connecting block 1001 to slide synchronously. Connecting block 1001 will slide against the inner wall of limit frame 9 to ensure stability during the sliding process. Connecting block 1001 serves to connect slider 8 and push rod 1002, so that push rod 1002 can slide synchronously through connecting block 1001. The sliding of push rod 1002 facilitates subsequent sealing treatment.

[0036] Reference Figure 4 , Figure 5 and Figure 6 The push rod 1002 has a rotatably connected bidirectional threaded post 15 inside, and a rotating block 16 is fixedly connected to one end of the bidirectional threaded post 15. The bidirectional threaded post 15 fixes the rotating block 16, and the bidirectional threaded post 15 can rotate synchronously by rotating the rotating block 16. A threaded block 17 is threadedly connected to the outer wall of the bidirectional threaded post 15, and the outer wall of the threaded block 17 is slidably connected to the inner wall of the push rod 1002. A slot 18 is opened inside the threaded block 17. A slot 21 is opened inside the push rod 1002, and the end of the push rod 1002 away from the connecting block 1001 is slidably connected to... A sealing plate 11 is fixedly connected to a sealing gasket 12 on its outer wall; one end of a connecting rod 13 is fixedly connected to the outer wall of the sealing plate 11, and a locking block 14 is fixedly connected to the other end of the connecting rod 13. The connecting rod 13 serves to connect the sealing plate 11 and the locking block 14. The outer wall of the locking block 14 is slidably connected to the inside of the push rod 1002, and the outer wall of the locking block 14 abuts against the inner wall of the slot 18; a spring 19 is fixedly connected between the threaded blocks 17 on both sides; an insert block 20 is fixedly connected to the outer wall of the sealing plate 11, and the outer wall of the insert block 20 abuts against the inner wall of the slot 21.

[0037] The usage process of the emergency taphole sealing device for a submerged arc furnace provided by this utility model is as follows:

[0038] The push rod 1002 supports the bidirectional threaded column 15. The rotation of the rotating block 16 allows the bidirectional threaded column 15 to rotate stably inside the push rod 1002. The bidirectional threaded column 15 is threadedly connected to the threaded block 17. When the bidirectional threaded column 15 rotates, the threaded blocks 17 on both sides slide against the inner wall of the push rod 1002. This tight fit ensures the stability of the threaded blocks 17 during sliding. A spring 19 is placed between the threaded blocks 17 on both sides. The sliding of the threaded blocks 17 compresses the spring 19, which acts as a buffer to prevent damage from over-tightening. When the sealing plate 11 needs to be installed, the locking block 14 is aligned with the push rod 1002 and slid into the push rod 1002. Through the connecting rod 13, the sealing plate 11 can be placed on the outer wall of the push rod 1002, allowing it to slide synchronously with the push rod 1002 to seal the furnace opening. A slot 18 is provided that can fully engage with the locking block 14. Reverse rotation of the rotating block 16 can cause the threaded block 17 to slide in the opposite direction. When the locking block 14 slides into the inner wall of the slot 18, it can be locked and fixed by continuous sliding. The sealing plate 11 plays a role in fixing the insert block 20. During the process of the locking block 14 sliding into the push rod 1002, the insert block 20 will also slide into the inner wall of the slot 21. The insertion of the insert blocks 20 on both sides can limit the position of the sealing plate 11, so as to avoid the situation where the sealing plate 11 rotates during the pushing process and affects the blocking effect. The sealing plate 11 is provided with a sealing gasket 12. Different materials of sealing gasket 12 can be selected according to different usage environments and needs. During the blocking process, the sealing gasket 12 will fit tightly with the furnace mouth of the electric arc furnace to form a good seal, effectively preventing molten iron leakage and high temperature gas escape, ensuring operational safety, and avoiding heat loss. The detachable and replaceable design makes it easy to select the appropriate sealing plate 11 according to different furnace mouths, which is suitable for different working conditions.

[0039] In this embodiment, each structure has its own service life. In actual manufacturing and application, the corresponding structure made of different materials can be replaced according to the needs of use.

[0040] In this embodiment, the motor is a self-locking motor, which can drive the connected structure to rotate normally when it is powered on and working. When the motor stops working, it can prevent the connected structure from rotating through its self-locking function.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
